Cloud seeding to make it snow harder and to increase snowfall over mountains is a well known process. Wikipedia has an article on it. Its possible to use planes, blimps and rockets fired form the ground to seed snow clouds over the arctic. Causing snowfall to increase can increase the amount of reflected sunlight and keep the permafrost frozen longer. Thawing permafrost is expected to cause huge increases in methane and CO2 released into the atmosphere. I have no idea what it will cost to keep the arctic frozen this way.
